The present study determined the growth patterns of the Juglans neotropica Diels species from the natural forest of Chachapoyas. Also identified the macroscopic and microscopic characteristics of wood of Juglans neotropica Diels and evaluated the influence of precipitation and temperature on the growth rings. The sampling was carried out in the department of Amazonas, in the districts of Leymebamba and Amazonas. The description of the anatomical structure of the wood of Juglans neotropica Diels was made as described by IBAMA (1991) and IAWA (1989); and the dendrochronological analysis of the growth rings was carried out using the programs CooRecorder, COFECHA, “Dendrochronology Program Library in R” and the R package “Treeclim”. This specie showed distinguishable growth rings. Its structure presents large pores at the beginning of the ring; followed by smaller pores; ending with bands of marginal parenchyma. The wood, at a macroscopic level, is classified as semi-ring-porous; straight grained and has medium texture; contains single and multiple radial pores from 2 to 3, and parenchyma in lines and marginal. At the microscopic level, wood is made up of medium pores with simple perforation and alternate polygonal intervessel pits; parenchyma in lines and marginal; heterocellular rays type II; and medium libriform fibers thin to thick walled. It was concluded that there is no influence of precipitation and temperature in the formation of growth rings for the studied area.
